At the beginning of season 1, Savannah was portrayed as a brown beagle with green eyes. However, in "New Girl In Town" (episode 4), she gets a makeover and becomes a reddish-brown dachshund with white and orange markings.
Savannah was a friendly girl for the majority of the series, but eventually, her personality shifted. Her popularity got to her head for a short time, and not long after, she mauls her enemy Brooklyn Hayes. Savannah acted sweetly at first, but, when her friends take her to get a makeover, she decides there's going to be a new Savannah Reed. Savannah then acts smooth and sarcastic, and she sticks up for herself. Savannah acts rough and, in some cases, savage, to Brooke sometimes, but when it comes to everyone else, she's somewhat kind. She often flirts with the boys and tries to be friendly around them. At Brooke Hayes' party, Savannah's opinion of Brooke changes when Brooke scratches her face. This makes Savannah dislike Brooke even more, yet she still cares, though very little. Savannah often thinks she's not good enough, or compares herself to others. Savannah was going anorexic, until Sage told her to stop and that he likes her for who she is, not her weight. In season 2, her feelings change when Brigitte LeBlanc, a new student from France joins the school. Savannah acts different and feels like Brigitte is stealing Sage, and Savannah gets very jealous and a bit insecure and unsure. Therefore, Savannah acts differently around Sage and Brigitte. But with her friends around, she's everyone's teenage girl. She also can be rather jealous and sometimes a wanna-be. She also did not want to be pushed around by Brooke and is, therefore, snappish and sharp.
Savannah is introduced as a 16-year-old girl from Montana. One day, she receives the good news that her family is moving to Orange County, in California.
Her best friend Brooklyn Hayes had also moved there in 8th grade. She is elated, especially when she discovers that she'll be attending the same school Brooklyn goes to. Despite gentle warnings from her mother, Mrs. Reed, that Brooklyn may have changed over the years, Savannah heads into school with a go-getter attitude, determined to restore her relationship with her long-lost BFF. There she meets Angelina Davis, a friendly cat who helps her decipher her schedule. Angelina introduces Savannah to her best friend Genevieve Ryan, and the three begin hanging out. At her first sight of Brooklyn, she runs up to her, hoping to have a tearful reunion, but instead is rejected. She dismisses it as a joke, and ignores Angelina and Genevieve's warnings that Brooke might not be the same person she was before. She later accepts the fact that Brooke is not interested in reviving their friendship, after Brooke pulls her aside to tell her.
After their previous 'incident', Brooke begins bullying Savannah about her looks.
To fight back, Genevieve gives Savvy the idea of getting a makeover. This, of course, is shot down by Savannah's mother. In "New Girl In Town" (episode 4), however, she accepts Savvy's plan, agreeing that Savannah should dye her hair red instead of bleach blond. The plan is put into motion, and when Savvy comes back to school, Brooke is shocked that she has competition and decides to up her game by having her friends 'ruin Savannah'. In "Calories and Competition" (episode 5), Savannah gets splattered with ink by Rachel Rivera, Brooke's friend. When the teacher tells Savannah to wash up, she meets Sage Bond, Brooke's boyfriend. After school, Savvy tells Genny and Lina that she has a crush on Sage, as they tell her to spend more time with him.
The next day at school, Savvy asks Sage if he can be her partner for an English project. He accepts and goes over to her house after school. When Brooke sees that Sage and Savvy are getting close, she starts spreading rumors about Savvy which lead to Sage to start avoiding her. Later on, Savannah meets Tom Dawson, who says that he doesn't believe in those rumors and wants to hang out with Savannah. Later the next day, Savannah takes her mother's advice and shows the whole school what "they're missing" by acting somewhat like a "mean girl". Savvy gets re-paired up with Tom for their English project, leaving Sage on his own. Tom then asks Savvy to sit with him at lunch. Savannah begins to re-gain popularity all over again. She then gets a phone call from Tom telling her to sit with him at lunch again. This time, he pulls Savannah up on to the table, asks her to be his girlfriend and gives her a necklace.Savannah decides to go to Brooke's "Party of the Century" with Genny, Lina and Tom. She also decides to skip school to give her friends makeovers for the party. She shows up at the party in an angel costume, with Genny and Lina with their new looks. She goes off to dance with Tom, but soon finds him cheating with Brooke. She cries and throws away the necklace he gave her, calling him a "Stupid cheater". Sage then finds Savannah crying and goes to Brooke's closet, where Brooke hid supplies for Savvy's torture. Sage apologizes to Savvy and confesses to her, as they start to make out. Brooke then finds them, along with Alicia and Tom. She attacks Savannah and cuts her face with her claws. After Sage defends her, Tom tells everyone the truth of his past, and that he was only trying to protect Savvy and not cheat on her. Savvy then leaves with Sage, who has just broken up with Brooke. As they approach the dance floor, the song of Brooke and Sage's 3rd year anniversary song comes on, and Sage dances with Savannah, much to Brooke's rage; she tells all her guests to leave.
Sage takes Savannah to the hospital and gets her stitches for her cuts that Brooke had made. He makes her give up her anorexia, as she agrees. Sage and Savannah have officially become boyfriend and girlfriend. A few weeks later, Savvy meets up with her friends, and talks about how Brooke hasn't been in school since the party, and Genny suggests that she transferred. Savvy then sees a girl with Sage, she goes over to meet the new exchange student from France, Brigitte LeBlanc Sage tells Savvy that she's his cousin. Brigitte corrects him and tells her that they've known each other since they were both babies, but Savannah still seems to feel threatened by Brigitte. After school, Savannah goes rollerblading and finds a lost cricket in the bushes, covered in cuts. She takes her home and with the approval of her mother, keeps her and names her Mimi. The next day at school, Savannah sees a note taped onto her locker which says "SAVANNAH- enjoy Sage while you can, he won't be yours 4 long. KISSES!" The same day at lunch, Savvy sees that Brooke had returned. After lunch, Savannah decides to show Sage the note that was on her locker. He thinks that it's Brooke's doing, but Savannah thinks it's Brigitte. Sage tells her it couldn't be her, because she has a boyfriend named Phillip back in France. Savvy and Sage eventually start to make out, only to be interrupted by Brooke. She gives him back his sweat-shirt he gave her to wear. She apologizes to Sage and Savvy, but obviously doesn't mean it. She gives Savannah a flower, but still makes fun of her by telling her she reminded her of a bunny; "cute; and chubby". Savannah growls at her, and Sage breaks up their fight and leaves for his next class. Savvy tells Brooke that she doesn't scare her, and tells her that the note she thought she wrote was "cute". Brooke denies this and leaves, calling Savannah a wiener-dog once again.
Savannah reaches home, only to be greeted by Mimi's whimpers. Her mother shows up and tells her that Mimi was scared that Savannah had left her for good.
Mimi has a flashback of Brooke not keeping her promise about coming back home to feed her in time. Mimi ends up leaving a dropping on the floor, for not being walked in a whole day.

Soon, Savannah goes over to Sage's house to give him his notes from school that he had mixed up with her's by accident, only to find him hugging Brigitte in his room. Sage tells Savannah that Phillip had broken up with Brigitte over the phone, and that he was only comforting her. Brigitte makes a comment about how she is "free to date all the cute boys in California", making Savannah worry. The next day, Savannah tells Lina and Genny about how she hasn't seen Tom since the party. Brooke then comes to mock Savannah once again, insulting her breed and making fun of her looks. Savannah believes Brooke and loses her confidence again. She then takes Mimi to school with her, because she cries whenever Savannah is away. Brooke then sees her and takes Mimi away, knowing that this is her cricket, Gigi. Savannah screams in horror, and runs after Brooke.
Savvy tries to get Mimi away from Brooke and knocks her over in the process and catches Mimi who flew through the air after Brooke had fallen. Savannah protects Mimi from Brooke but she manages to snatch her back, Savannah does the same, and Brooke grabs the cricket again, only to be bitten by her. Mimi runs back to Savannah. Savvy lets Mimi choose who she would rather go with and she chooses Savvy. Savannah decides to take Mimi back home, but is stopped by Brooke, who grabs Savannah with her claws and demands her to hand over the cricket. Savannah bites Brooke reflexively and Brooke swipes her face, in response, then grabs Savannah with her claws again. Savannah pushes Brooke and she slams into a locker, leading to her fall on the floor, bleeding and unconscious. Savannah is horrified by this. After this, Brooke gets up and Savvy keeps saying thats she is really sorry, Brooke is really mad and tells everybody what Savvy did.
Savannah is now seen in her house, with her mother and father. Her father explains she was suspended from school for an unknown time, and that she put Brooke in the hospital.
